OIL-SUPPLY SYSTEM FOR BURNERS.

SPECIFICATION forming part of Letters Patent No. 631,077, dated August15, 1899.

Application filed April 7,1899- Serial No. 712,086. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL LEWIS J ONES, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in a Combined Vacuum-Ohamber, Oil-Tank, and Pressure-Pu mp for Returning the Oil fromService-Lines, which improvement is fully set forth in the followingspecification and accompanying drawings.

My invention consists of an improved construction of combinedvacuum-chamber, oiltank, and pressure-pump whereby I am enabled toreturn the oil or hydrocarbon from service-lines, so that .when theoil-supply is shut off from the burners the service-line can beexhausted of oil until such time as it shall be desired to start thelights again, whereby the objectionable feature of having theservice-lines full of hydrocarbon after the lights are extinguished isobviated by my invention.

It further consists of novel details of construction, all as will behereinafter fully set forth, and particularly pointed out in the claims.I

Figure 1 represents a side elevation, partly broken away, of a combinedvacuum-chamber, oil-tank, and pressure-pump embodying my invention.Figs. 2 and 3 represent sectional views of a three-way valve employed,showing the same in difierent positions which it may assume.

Similar letters of reference indicate corresponding parts in thefigures.

Referring to the drawings, A designates an oil-tank, the same beingprovided with a gage 1 whereby the height of the oil or hydrocarbontherein can be readily ascertained.

O designates an outlet-pipe, the lower end of which latter dependsnearly to the bottom of the tank A, which latter is replenished with oilor hydrocarbon through the opening O which latter is provided with asuitable closure.

D designates a fitting into which the pipe 0 discharges, said fittingbeing provided with a valve D a gage E, and a branch F, which has avalve G therein, from which latter leads the service-pipe H to thethree-way valve J, the latter having a plug K therein which is providedwith the port L, extending transversely through said plug, said port Lhaving the port M situated at an angle thereto, which latter port isadapted to be turned into communication with the pipe N or P, as will beunderstood from Figs. 2 and 3.

The pipe P leads from the valve J and discharges into the vacuum-chamberQ and is provided with a valve R, while said chamber has a pipe Tleading from the lower portion thereof to the air-pump V, said pipebeing provided with the valve U, and said vacuumchamber having anair-cock S at its upper portion.

W designates a pipe leading from the upper portion of the air-pump tothe upper portion of the hydrocarbon-tank A, said pipe W being providedwith a valve X.

The operation is as follows: When it is desired to pump air into theoil-tank A, the

valve R is closed and the cock S and valves X and U are opened,whereupon it will be seen that upon the operation of pumping air will beforced into the upper portion of the oil-tank A. When the desiredpressure has been attained in the oil-tank, the cock S is closed, afterwhich the air is exhausted from the chamber Q, thus makingavacuum there-'in, after which the valve U is closed. The

valves D and G being open and the plug K of the valve J being in theposition seen in Fig. 2, the system is now ready for lighting. Toextinguish the lights and return the oil out of the service-line Nto thevacuum-chamber Q, the valve G is closed, the valve-plug K is turned intothe position seen in Fig. 3, and the valve Ropened. The lights willinstantly be extinguished, and the oil in the servicelines will returnto the vacuum-chamber Q. To return the oil from the vacuum-chamber Q,the cock S opened and also the valves U and X and the pump operated, theeffect of which is evident.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is l 1. The combination of an oil-tank, avacuumchamber, an air-pump, valved connections common to said oil-tankand vacuumchamber, a valved pipe common to said oil- 2. In a device ofthe character named, an oil-tank, a vacuum-chamber, a valved servicepipeleading from said oil-chamber, a valved connection from said servicepipe to said Vacuum-chamber and from the latter to an air-pump, and avalved connection from said air-pump to said oil-tank.

3. The combination of an oil-tank ,a vacuum-chamber adjacent thereto,said chamber having an air-cock at its upper portion, a service-pipeleading from the upper portion of said oil-tank, an air-pump, a pipeleading from said air-pump to the upper portion of said oil-tank, a pipeleading from said service-pipe to the upper portion of saidvacuumehamber, a three-way valve at the junction of said latter pipes,and a valved pipe leading from the lower portion of said vacuumehamberto said air-pump.

4. The combination of an oil-tank having a pipe leading upward from thelower portion thereof and connecting with a service-pipe, a three-wayvalve in said service-pipe, a valved connection from said three-wayvalve to the upper portion of a vacuum-chamber, an aircock in the upperportion thereof, an airpump, a valved connection from the lower portionof said vacuu m-chamber to said pump and a valvedconnection from saidpump to the upper portion of said oil-tank.

5. The combination of an oil-tank, pressure pump, vacuum chamber andserviceline, with means for causing the return of the oil or hydrocarbonfrom said service-line, whereby the latter can be exhausted of oil whenthe oil supply is shut off from the burners.

SAMUEL LEWIS JONES.
